We can use any wirenut color we want here, any size, any push-in, anything as long as it's connected properly.

Are push-ins legal there? What if you only have two wires, you still have to use a big Greenie, or what? What if you (even more likely) have more wires than fit in a Greenie? Do you have to use more than one and wire the two together? Yeah, that's safer....

If a person is building his own (custom) home and cost is not an issue.......is it acceptable to use 12/2 wire with 20 amp receptacles and 20 amp breakers on every outlet? Or is there code that requires 15 amp circuits in certain locations and 20 amp circuits in other locations.
Thanks,

A few month ago I had a new HVAC unit installed in the attic. In the process of the installation the electrician installed a new outlet near the HVAC unit. The outlet seemed to be very good quality and I asked who made them but have since forgotten. The connecting screws had square wahers under them and to make the connection you just slide a straight wire beneath the washer and tightened the screw. I have numerous residential(junk) grade outlets to replace and thought these would be good.
Who makes these and can they be found at the local super stores? Are they good outlets.
